Inventor: UCHIKOGA HIROSHI
IPC: G09G1/16
Filed: 1991-08-08
Abstract: According to this invention, a panel controller converts display data having 64 gray scale levels for a color CRT output from an RAMDAC into display data having 57 gray scale levels to perform display driving of a color LCD. The panel display controller has a function of generating 7 intermediate pseudo gray scales between the base frames of R, G, and B signals by a frame rate control method in the color LCD having 8 base gray scale levels of each of the R, G, and B signals to generate (180 K colors) display data having 57 gray scale levels and a function of generating 3 intermediate pseudo gray scales between the base gray scales of the signals by a dither method to generate (24K colors) display data hav-ing 39 gray scale levels.  The selection of the frame rate control or the dither method and the selection of the 512-color, 180-K-color, or 24-K-color display are arbitrarily performed, or these selection operations are automatically performed in accordance with a display mode.
Patent CA-2052835-A1 (CA)
Inventor: HARA TAKAHISA
IPC: B29C45/57
Filed: 1991-10-04
Abstract: The present invention is directed to a method of producing a foamed article of a polypropylene resin.  The method comprises the steps of providing a pair of male and female molds which are slidably engaged and which have a freely set cavity clearance.  A polypropylene resin melt containing a chemical blowing agent is supplied to the male or female mold when the cavity clearance is 1.0 mm or less.  One of the molds is moved to increase the cavity clearance while the polypropylene resin is being supplied so that the pressure on the resin melt is adjusted in a range between 5kg/cm2 and 100kg/cm2. As soon as the resin supply is finished pressure is applied to form a skin layer on the resin melt and further increasing the cavity clearance to form a foamed core layer.          The foamed article is allowed to cool in the mold.  The method of the present invention is suitable for preparing embossed polyvinyl chloride leather lined with a fabric.

Title: Compositions useful in inhibiting generation, maturation, motility and viability of sperm with minerals in biovailable form
Inventor: FAHIM MOSTAFA S
IPC: A61K47/18
Filed: 1991-10-18
Abstract: A cell permeable physiologically acceptable water soluble mineral salt of a carboxylic acid such as zinc acetate, calcium acetate, zinc gluconate and the like having a pH in the range of 6.0 to 7.5 capable of forming a stable solution under ambient conditions at pH 7.0 is bioavailably effective at inhibiting the generation, maturation, motility and viability of sperm when applied to sperm or developing sperm in the testis, epididymis or vas deferens of a male subject or the vagina, cervix, uterus or fallopian tubes of a female subject. When the subject is a male subject and the mineral salt is zinc gluconate or the like and is injected into the testis or epididymis, the stability and efficacy of the mineral salt at pH 7.0 is improved by the presence of an amino acid such as arginine which acts as a permeation enhancer. <IMAGE>

Abstract: ABSTRACT     COUPLING DEVICE TO BE CONNECTED TO A DCE FOR ALLOWING THE CONNECTION TO DIFFERENT PUBLIC SWITCHED TELEPHONE   NETWORKS, DCE AND WORKSTATION INCLUDING THE SAME            Coupling device according to the invention for connecting a DCE to a PSTN including the electronic components matching the electric requirements of a specific PSTN. The coupling device comprises plugging means for removably connecting the latter to the DCE, means for storing an identification code corresponding  to  a  specific  type  of  PSTN  to  which  the coupler is intended to be connected to. The coupling device further  comprises  means  responsive  to  a  control  signal received from the DCE for transmitting the identification code to the DCE. The DCE connected to the coupling device includes processing means and a storage for storing tables, each table comprising data characterizing a specific PSTN which the DCE is intended to operate with. The DCE reads the identification  code  during  an  identification  phase  by transmitting the control signal and selects in response to said  reading the  appropriate  table  corresponding to  the coupling  device.   Therefore,   by  simply  connecting  an appropriate  coupling  device,  a  same  DCE  can be  easily adapted to operate with a specific PSTN. Moreover, since the voluminous components are located into the coupling device, the  DCE  can  be  easily  integrated,  for  example  in  one workstation.

Title: Variable speed transmission device, particularly for motor vehicles
Inventor: ANTONOV ROUMEN
IPC: F16H3/62
Filed: 1991-02-27
Abstract: A motor (3) drives the pump (8) of a torque converter (7), the turbine (11) of which is connected to the crown (16) of a planetary gear train (13), the satellite carrier (18) of which is connected to the output of the transmission.      The pump (8) is connected to the planet wheel (14) of the planetary gear train (13). The crown (16) is mounted on a free wheel (22) preventing rotation in the backward direction. During starting, the power passes via the planet wheel (14) into the gear train (13) which behaves as a mechanical reducer with the crown (16) immobilised by the free wheel (22). Then, the torque transmitted by the converter to the crown (16) exceeds the reaction torque strictly necessary, and the speed of the crown (16) becomes progressively equal to that of the planet wheel (14). The gear train (13) operates as an adder of the powers received mechanically at the planet wheel (14) and hydraulically at the crown (16). An automatic direct drive (23) is provided.      The invention is used for minimising the control, the losses in the converter, the weight, cost and bulk.

Title: Method for handoff in a mobile radio communication system
Inventor: ISRAELSSON PER V
IPC: H04W36/30
Filed: 1991-02-18
Abstract: The invention relates to a method in connection with handoff from a first base station (1) in a mobile radio communication system, in which method the signal strengths from a set of base stations (1) surrounding a mobile station are measured in the latter. When handoff is considered to be motivated, the signal strength vector formed by the measured signal strengths is correlated with stored characteristic signal strength vectors associated with the first base station (1).  If the correlation between measured signal strength vector and one of said stored characteristic signal strength vectors exceeds a predetermined correlation level, handoff is commanded to a predetermined second base station (2-7) in the set having acceptable but not the highest signal strength in the measured signal strength vector, or is the handoff procedure interrupted and the connection between the mobile station and the first base station (1) maintained.

Title: Method for monitoring weld quality in mash seam welding
Inventor: SCHREINER JUERG
IPC: B23K9/095
Filed: 1992-10-27
Abstract: METHOD FOR MONITORING WELD QUALITY IN MASH SEAM WELDING            ABSTRACT          When mash seam welding sheet-metal plates (11,12) with overlapping edges between roller electrodes (13,14), the quality of the weld - given that the process parameters (compressive force F of the roller electrodes, rate of advance v, current intensity I through the weld) are observed and/or controlled - is also dependent upon the width of overlap (b) of the plate edges at  the weld joint.  Because it is difficult to measure the actual overlap in production, the thickness (ts) of the weld seam is recorded by way of a substitute.  For given workpiece data and corresponding weld parameters, this thickness is in direct correlation with the width of the overlap (b).     The functional correlation ts = f(b) can be established empirically and enables the actual value of the overlap to be calculated on the basis of the seam thickness measured.          The thickness of the seam may either be measured at the weld location by measuring the spacing of the roller electrodes (position encoder 16) or at the finished weld seam (measuring device 17).  In place of the correlation ts = f(b) it is also possible to evaluate the correlation of ts with another operating parameter in analogous fashion.
